* | ethtool: Define and apply a default policy for RX flow hash indirectionBen Hutchings2011-12-164-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All drivers that support modification of the RX flow hash indirection table initialise it in the same way: RX rings are assigned to table entries in rotation. Make that default policy explicit by having them call a ethtool_rxfh_indir_default() function. In the ethtool core, add support for a zero size value for ETHTOOL_SRXFHINDIR, which resets the table to this default.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add a new ethtool operation (get_rxfh_indir_size) to get the indirectional table size. Use this to validate the user buffer size before calling get_rxfh_indir or set_rxfh_indir. Use get_rxnfc to get the number of RX rings, and validate the contents of the new indirection table before calling set_rxfh_indir. Remove this validation from drivers.

Also, remove the support for the auto-configuration. I'm not aware of anyone using it, and it ends up using the bus mutex before it's been initialized.

All these uses assume it's always the id of fec device which is >= 0. However this is only true for non-DT case. When DT plays, pdev->id is always -1, which will break these pdev->id users. Instead of fixing all these users one by one, this patch introduces a new member 'dev_id' to 'struct fec_enet_private' for holding the correct fec device id, and replaces all the existing uses of pdev->id with this dev_id.

Added module parameters sr_iov and probe_vf for controlling enablement of SRIOV mode. 2. Increased default max num-qps, num-mpts and log_num_macs to accomodate SRIOV mode 3. Added port_type_array as a module parameter to allow driver startup with ports configured as desired. In SRIOV mode, only ETH is supported, and this array is ignored; otherwise, for the case where the FW supports both port types (ETH and IB), the port_type_array parameter is used. By default, the port_type_array is set to configure both ports as IB. 4. When running in sriov mode, the master needs to initialize the ICM eq table to hold the eq's for itself and also for all the slaves. 5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap. 6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca). VFs obtain their startup information from the PF (master) device via the comm channel. 7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver aborts loading the device. 8. Do not allow setting port type via sysfs when running in SRIOV mode. 9. mlx4_get_ownership: Currently, only one PF is supported by the driver. If the HCA is burned with FW which enables more than one PF, only one of the PFs is allowed to run. The first one up grabs a FW ownership semaphone -- all other PFs will find that semaphore taken, and the driver will not allow them to run.

Virtual functions (VFs) are attached to guest operating systems but resources are allocated from the same pool and are assigned to VFs. It is essential that hostile/buggy guests not be able to affect the operation of other VFs, possibly attached to other guest OSs since ConnectX firmware is not tolerant to misuse of resources. The resource tracker module associates each resource with a VF and maintains state information for the allocated object. It also defines allowed state transitions and enforces them. Relationships between resources are also referred to. For example, CQs are pointed to by QPs, so it is forbidden to destroy a CQ if a QP refers to it. ICM memory is always accessible through the primary function and hence it is allocated by the owner of the primary function. When a guest dies, an FLR is generated for all the VFs it owns and all the resources it used are freed. The tracked resource types are: QPs, CQs, SRQs, MPTs, MTTs, MACs, RES_EQs, and XRCDNs.

Wrapper functions: mlx4_MAP_EQ_wrapper Only the master can map an EQ. The slave commands to map their EQs arrive at the master via the comm channel. The master then invokes the wrapper function to do the work (and enter the resource in the tracking database). New events: COMM_CHANNEL and FLR The COMM_CHANNEL event arrives only at the master, and signals that a slave has posted a command on the comm channel. The FLR event is generated by the FW when a guest operating a VF unexpectedly goes down. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: David S.

QUERY_FUNC_CAP and its wrapper. This function is used by VFs when they start up to receive configuration information from the PF, such as resource quotas for this VF, which ports should be used (currently two), what protocol is running on the port (currently Ethernet ONLY, or port not active). 2. QUERY_PORT and its wrapper. Previously, this FW command was invoked directly by the ETH driver (en_port.c) using mlx4_cmd_box. Virtualization is now required here (the VF's MAC address must be substituted for the PFs MAC address returned by the FW). We changed the invocation in the ETH driver to use mlx4_QUERY_PORT, and added the wrapper. 3. QUERY_HCA. Used by the VF to determine how the HCA was initialized. For now, we need only the multicast table member entry size (log2_mc_table_entry_sz, in the ConnectX PRM). No wrapper is needed here, because the data may be passed as is to the VF without modification). In this command, we have added a GLOBAL_CAPS field for passing required configuration information from FW to a VF (this field is to allow safely adding new SRIOV capabilities which require support in VF drivers, too). Bits will set here by FW in response to PF-driver configuration commands which will activate as yet undefined new SRIOV features. The VF will test to see that all required capabilities indicated by this field are supported (i.e., if a bit is set and the VF driver does not recognize that bit, it must abort its initialization). Currently, no bits are set. 4. Added a CLOSE_PORT wrapper. The PF context needs to keep track of how many VF contexts have the port open. The PF context will not actually issue the FW close port command until the last port user issues a CLOSE_PORT request.

* | | | net/mlx4_core: Implement the master-slave communication channelYevgeny Petrilin2011-12-131-27/+672
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When SRIOV is enabled, pf and vfs communicate via shared comm channel. The vf gets its side of the comm channel via a VF BAR. Each VF (slave) creates its vHCR (virtual HCA Command Register), Its DMA address is passed to the PF (master) using Communication Channel Register. The same Register is used to notify the master of commands posted by the slaves and for the master to pass events to the slaves, such as command completions and asynchronous events. The vHCR format is identical to the HCR format, except for the 'go' and 't' bits, which are reserved in the vHCR. Posting commands to the vHCR is identical to the way it is done with the HCR, albeit that the function/PF token fields are used instead of the HCR go bit. Specifically: - When the function prepares a new command in the vHCR, it issues the Post_vHCR_cmd communication channel command and toggles the value of the function token; when PF token has an equal value, the command has been accepted and a new command may be posted. - When the PF detects a Post_vHCR_cmd command, it concludes that a new command is available in the vHCR; after processing the command, the PF toggles the PF token to match the function token. When the 'e' bit is not set, the completion of a Post_vHCR_cmd command also indicates the completion the vHCR command. If, however, the 'e' bit is set, the completion of a Post_vHCR_cmd command only indicates that the vHCR command has been accepted for execution by the PF. Function commands are processed by the PF as follows: -DMA (using the ACCESS_MEM command) the vHCR image into a shadow buffer. -Validate that the opcode is non-privileged, and that the opcode- and input-modifiers are legal. -DMA the in-box (if required) into a shadow buffer. -Validate the command: o Resource ranges (e.g., QP ranges). o Partition key. o Ranges of referenced resources (e.g., CQs within QP contexts). -If the 'e' bit is set o complete the Post_vHCR_cmd command -Execute the command on the HCR. -DMA the results to the vHCR out-box (if required). -If the 'e' bit is set o Indicate command completion by generating a completion event using the GEN_EQE command -Otherwise o DMA the command status to the vHCR o Complete the Post_vHCR_cmd command Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Yevgeny Petrillin <yevgenyp@mellanox.com> Signed-off-by: Liran Liss <liranl@mellanox.com> Signed-off-by: David S.

* | | | mlx4_core: Reduce number of PD bits to 17Jack Morgenstein2011-12-132-6/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When SRIOV is enabled on the chip (at FW burning time), the HCA uses only 17 bits for the PD. The remaining 7 high-order bits are ignored. Change the allocator to return only 17 bits for the PD. The MSB 7 bits will be used to encode the slave number for consistency checking later on in the resource tracker. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: David S.

* | | | mlx4_core: Add "native" argument to mlx4_cmd and its callers (where needed)Jack Morgenstein2011-12-1313-55/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For SRIOV, some Hypervisor commands can be executed directly (native = 1). Others should go through the command wrapper flow (for tracking resource usage, for example, or for changing some HCA configurations that slaves need to be notified of). This patch sets the groundwork for this capability -- adding the correct value of "native" in each case. Note that if SRIOV is not activated, this parameter has no effect.

* | | | xen-netfront: delay gARP until backend switches to ConnectedLaszlo Ersek2011-12-121-1/+3

However, if the packet appears on the backend interface before the backend is added to the target host's bridge, the packet is lost, and the migrated guest's peers become unable to talk to the guest. A sufficient two-parts condition to prevent the above is: (1) ensure that the backend only moves to Connected xenbus state after its hotplug scripts completed, ie. the netback interface got added to the bridge; and (2) ensure the frontend only queues the gARP when it sees the backend move to Connected. These two together provide complete ordering. Sub-condition (1) is already satisfied by commit f942dc2552b8 in Linus' tree, based on commit 6b0b80ca7165 from [1]. In general, the full condition is sufficient, not necessary, because, according to [2], live migration has been working for a long time without satisfying sub-condition (2). However, after 6b0b80ca7165 was backported to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6 guest. This patch intends to provide (2) for upstream.
